Thermal Expansion Coefficients Relation – Rankers Physics

Thermal Expansion: Practice Problem & Solution

The relation between coefficient of linear expansion (\(\alpha\)) and coefficient of volume expansion (\(\gamma\)) for solids is
\(\gamma = 2\alpha\)
\(3\gamma = \alpha\)
\(\gamma = 3\alpha\)
\(2\gamma = 3\alpha\)

Solution Explained:

To solve this problem, we apply the core principles of Thermal Expansion. Understanding the underlying formula is key to arriving at the correct answer below:

Coefficient of volume expansion is three times the coefficient of linear expansion for an isotropic solid, i.e., \(\gamma = 3\alpha\).
